Definitions
- the invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 11.
- the invention is concerned with concrete pumps, especially truck-mounted concrete pumps, but is not limited to the promotion of concrete but generally applicable to the promotion of thick materials, such as sludges of any kind and the like.
- Both in building construction as well as civil engineering concrete pumps of various types and with different performance design are used to deploy locally supplied mostly by mixer vehicles concrete for the formation of walls, ceilings and the like.
- Both stationary concrete pumps and movable concrete pumps, in particular so-called truck-mounted concrete pumps, are used here.
- the pump In the case of truck-mounted concrete pumps, the pump is arranged on the frame or the bed of a lorry and sucks concrete from a filling hopper arranged on the vehicle, which is then applied to the construction site via an outgoing conveyor line.
- Such truck-mounted concrete pumps usually have a mast boom, which is composed of several articulated mast arms connected to each other, which can be pivoted to save space, so that the mast arms of the mast boom more or less parallel, but in a confined space merged on the frame or the bed are arranged and thus a road transport is readily possible.
- This mast boom are mounted on a turntable via a tilting joint, which in turn is rotatably mounted about a vertical axis on the vehicle frame, in particular on a fixed to the vehicle mast bracket.
- the turntable with the tiltable hinged and swingable mast boom can be Extend the mast arm by unfolding the mast arms and rotate or swivel spatially over 360 ° around the axis of rotation of the fifth wheel.
- the once positioned vehicle can supply a very large area with concrete.
- a limit switch is used here for determining the angle of rotation, which is mounted on the outer circumference of the turntable of the fifth wheel. It is disadvantageous in this embodiment that thus always only one end position of the system is detected. Furthermore, this system does not provide any redundancy in the event of system failure. Above all, this system is not suitable for the measurement of a plurality of intermediate positions of the turntable, because it would require a significant number of limit switches. However, this would involve a great deal of effort for the wiring of the components and the entire assembly.
- the position of the turntable is detected by means of two mounted on the outer circumference rotary angle meter, each with its own drive and between are provided geared transmission. Although it can be reliably measure the position of the turntable in any position and also provide the required redundancy for this system, but a high production cost is required. In addition, these Drehwinkel- takers build relatively large and also have a relatively high weight, which is disadvantageous in the course of a lightweight construction of the overall machine. Overall, this system is thus comparatively expensive.
- the object of the invention is to provide a device and a method which allows in a simple and very reliable manner an accurate determination of the angular position of the fifth wheel with a mast arm arranged thereon. At the same time, redundancy is to be ensured and the execution must take place in a space-saving and weight-saving manner.
- the number of revolutions of the drive shaft of the drive or a shaft of a connected thereto gear for the drive of the fifth wheel and not the turntable is tapped directly.
- simple sensors advantageously two or four sensors, without this being limiting, wherein the triggered pulse signals can be counted in a simple manner.
- two sensors it is possible to determine both the direction of rotation, ie the direction of rotation, of the drive shaft and thus of the fifth wheel as well as the angle of rotation itself.
- an upward or downward counting takes place. With these counts can be determined via an evaluation unit readily taking into account the special drive geometry, in particular geometry of the gearbox and with a turntable on the turntable cooperating output pinion of the transmission, the exact position of the turntable including the respective direction of rotation.
- the angle measuring system thus utilizes the already existing drive, which is usually formed by a hydraulic drive or hydraulic motor, including the existing there gear, the output gear is in engagement with the turntable of the fifth wheel.
- the pulse is input via a cam, the rotationally fixed on the Drive shaft or a transmission shaft, in particular the transmission output shaft, is arranged and the Tastnocken is then tapped by placed around the cam disk sensors.
- This allows a simple pulse count done, which is enumerating or counting depending on the direction of rotation.
- sensors in particular digital sensors, as they are readily available on the market in a cheap manner.
- the extra effort that results from this system is thus solely due to the additionally politicianflanschende cam and the sensors due, which can be used in a small size.
- the Tastnocken are formed by radial edges or shoulders of the cam.
- the edges trigger the sensors and generate the corresponding pulse signals which can be fed to a suitable evaluation unit. It is possible with two sensors both to detect the respective direction of rotation, ie forward or backward, and also to record the corresponding rotational angle values. The determination of the rotational angle then takes place by a simple multiplication with the resolution or parameters caused by the gear geometry. Due to pulse multiplication results in a very small resolution, which allows an exact sensitive rotation angle determination.
- four sensors are used, which are preferably grouped at an angular distance of 90 ° about the cam.
- Such a measuring system has the advantage that, in the event of a sensor failure, both the direction of rotation and the angle of rotation value are recognized by pulses, and thus a further determination of the angle of rotation is possible even in the event of the failure of a sensor. This results in a mutual monitoring of the plausibility of the multiple sensors.
- the inventive method is characterized by the count of the triggered pulses implied by the flanks of the cam, which is counted in the case of multiple sensors depending on the direction of rotation up and down and thus at any pivoting of the turntable nevertheless the exact rotational position can be determined.
- the invention is particularly applicable for truck-mounted concrete pumps with mast extenders with multiple boom arms, but also for stationary concrete pumps with turntable and mast boom.
- the rotation angle determination can be carried out in a simple manner using an evaluation unit, which has a computer for counting the pulses and a multiplier, the Counting in consideration of the special geometry of the fifth wheel drive, which is due to the transmission gear and the ratio between the drive pinion and slewing ring, and can convert the resolution thus initiated into the respective rotational angle value.
- the resting position of the mast arm in the mast support is used as the reference point, in which the mast arm is usually positioned in the longitudinal direction of the vehicle axle and stored in a mast support.
- the measuring system can be implemented in a simple manner on existing vehicles and is unique in the count, which is appropriate for an accurate position determination.
- the invention is characterized by a simple and robust construction. Since conventional sensors can be used without problems as sensors, the cost factor due to this additional measure is also very low. This is favored by the fact that the tap directly over the existing drive and gearbox takes place.

- Figure 8 is a schematic block diagram of a measuring device.
- Figure 1 shows a so-called truck-mounted concrete pump, in which case only parts are shown, which are required for the understanding of the invention.
- truck-mounted concrete pumps are well known and are characterized in that the concrete pump is mounted on a truck.
- the truck-mounted concrete pump is generally designated 1, which has arranged on the vehicle frame concrete pump 2 and also arranged on the frame turntable 3, which is rotatable about its central vertical axis 4 in different angular positions, and one designated 5 and here made of several mast arms trained mast boom 5 carries. On this mast boom 5, the concrete delivery line 6 is mounted.
- the mast boom 5 is tiltably mounted on the turntable at 6a via a tilting joint, so that the mast boom 5 from the rest position in Figure 1 in the apparent from Figure 2 tilting position is überfarbar, wherein the tilting movement is indicated by arrow K. ,
- the drive for the fifth wheel 3 is denoted by 12, which is usually a hydraulic motor here.
- the output shaft of the engine 12 is designated 14.
- the output shaft of the engine 12 leads into a transmission, of which, for the sake of simplicity, only the pinion 15 arranged on the transmission output shaft is shown in FIG. 8, the teeth of the pinion being only indicated.
- the pinion 15 cooperates with a turntable 3 arranged, here only schematically illustrated turntable 16, which is formed circumferentially around the stool 3 and provided with a corresponding toothing 16a, which is shown in Figure 8 for the sake of simplicity only partially.
- the pinion 15 cooperates with the teeth of the turntable 16 of the fifth wheel 3 for the purpose of the rotary drive of the fifth wheel.
- a cam disk which can be seen in plan view from FIGS. 4 and 6, is rotatably arranged on the motor shaft 14 and rotates with the shaft 14.
- the cam can also be arranged on one of the transmission shafts.
- Sensors or proximity switches 18 are grouped around the cam disk 17, of which only two sensors 18 present in this embodiment are shown in FIG.
- the sensors scan the rotating cam disc, which is provided with appropriate Tastnocken.
- a Tastnocke passes the sensor, there is a pulse in the sensor 18, which gives via line 19 a corresponding pulse signal to an evaluation unit 20 shown here as a block image.
- a second signal line 21 is shown.
- FIGS. 4 and 6 show an embodiment of a cam disc.
- the Tastnocken formed by radially extending shoulders 23 and 24 which are angularly offset from each other by 180 °.
- two Tastnocken are shown in the form of radial shoulders 23 and 24, which cooperate with two sensors 18 and 26.
- These sensors 18 and 26 are, as shown in FIGS 4 and 6, offset by 90 ° to each other and aligned radially to the center 27 of the cam.
- the center of the cam disk coincides with the shaft axis.
- the cam disc is driven at the same speed as the drive shaft 14 and thus at the same speed.
- the radial shoulders 23 and 24 are directed differently, wherein in the direction of rotation in clockwise direction shown in Figure 4 by clockwise rotation, the radial shoulder 23 is a leading and the radial shoulder 24 is a trailing shoulder. Accordingly, different switching signals are given, wherein the radial shoulder 23 is a designated "high” switching signal and the radial shoulder 24 in the diagram in Figure 5 with "low” designated switching signal.
- sensors common sensors are used here, in particular digital sensors.
- the sensors can be designed as inductive or capacitive sensors.
- a switching pulse "high” is given as soon as the radial shoulder or Tastnocke 23 passes the sensor 26, which represents the track 2 in the circuit diagram of Figure 5.
- FIG 5 is shown at the angular position 0 ° with the arrow pointing upwards, as soon as the radial shoulder has continued through 90 °, the shoulder 23 passes in front of the sensor 18 designed as track 1, so that for the track 1 in the shift diagram according to FIG from 90 °, a switching pulse "high” is given, as shown by the arrow in the diagram of Figure 5 and the track 1.
- pulses 1, 2, 3 and 4 increase the incremental count of the pulses per pulse by one counter and then count down by one counter in the reverse direction of rotation according to FIG the pulses 5, 6, 7 and 8.
- This incremental pulse count is, as indicated in Figure 8, placed in an evaluation unit 20, where the count is accomplished, that is counted depending on the direction of rotation up or down according to the pulses.
- the current angle value is then calculated depending on the geometry of the fifth wheel drive and indeed by multiplying the count with the resolution, which is dependent on the transmission data, ie from the ratio of the transmission, from the number of teeth of the turntable into engagement standing pinion 15 of Figure 8 and the number of teeth of the turntable, resulting in the translation of the slewing results. From this, the total ratio can be calculated, and thus the mechanical resolution per revolution of the gear drive. In a practical embodiment, which is only mentioned here by way of example, results from the gear geometry, for example, a resolution of 0.433 ° per revolution of the gear drive. As a result of the pulse quadrupling then results in a measuring device, as shown with reference to Figures 4 to 7, a resolution of 0.109 per pulse.
- four sensors are advantageously used instead of two sensors, which are arranged offset by 90 ° to each other around the cam disk around.
- This embodiment has the advantage of increased security. If one of the sensors fails, then a lesser degree of resolution results, but nevertheless both the direction of rotation and the angle of rotation are detected and counted. That is, the pulse count continues to run, albeit at a lower resolution with respect to the angle value. At the same time it can be seen that a sensor has failed, which can then be easily replaced. As a result, the security level can be increased accordingly without great effort.
- the described measuring device thus results in a clear pulse count, which can be determined by simple multiplication according to the gear geometry used an exact rotational angle value for each position of the fifth wheel at any time.
- sensors of conventional design can be used, which are extremely inexpensive, so that the cost of the measuring device are comparatively low.
- the pulse sequence is clearly defined, that is, in the direction of rotation left, the pulses always occur in the sequence 1, 2, 3, 4 and then again 1 and so on. In the opposite direction of rotation always the sequence 5, 6, 7 and 8 and then again 5, etc.
- the sequence is unique, that is, when reversing to pulse 1 pulse 2 must follow, after 2 follows 3, etc.
- the data that is important for the detection is permanently stored in the system, it can also be detected beyond the switched-off state if the system behaves correctly.
- the invention is not limited to truck-mounted concrete pumps but also applicable to stationary concrete pumps, which are equipped with a turntable for the Auflagerung a mast boom.
